So the pump was running last week. I turned it off so I could hook up the hose to do a water change, plugged it back in and nothing. Blah blah I didnt have time to deal with it so it sat in the water for a week unplugged. Well yesterday I go to do the water change, plug it in and POP the breaker trips. I figure maybe something got by the mech filtrations and logged in the propeller or magnet. Take it apart, nada. Put it back together, plug it in POP goes the breaker again. Whats going on? I just replaced the ceramic shaft 4 weeks ago due to my fault of breaking the end off while cleaning it.
